SIPHON BOTTLE HEAD Filed May 15, 1935 INVENTOR HARRY I 5corr.

Patented Apr. 21, 1936 UNITED STATES- PATENT OFFICE SIPHON BOTTLE HEAD Harry Scott, San Francisco, Calif. 7 Application May 13, 1935, Serial No. 21,070 Claims. (01. 215 -5) This invention relates to a cap or head for siphon bottles, which bottles are also known as Seltzer bottles and are commonly used as containers for carbonated liquid or Seltzer water or the like in which gas released from the liquid forces the liquid through the head upon opening a valve that is included in the head.

The objects of the invention are to provide a construction for a siphon bottle head whereby any metal suitable for casting may be used for the body of the head, and also to provide a valve arrangement that will permit filling the bottle with liquid and ejecting it therethrough without unnecessary loss of gas from the liquid, and which valve construction insures against leakage over a long period of hard usage. Other objects and advantages will appear in the drawing and specific'ations. In. the drawing, Fig.'1 is a plan view of my improved siphon bottle head.

Heretofore, siphon bottle heads have generally been constructed from a special and expensive tin alloy to insure'against objectionable efiects of the liquid ordinarily used in siphon bottles. I have overcome the necessity for using such metals by a specially constructed liquid conduit of cheap material, such as rubber, which is impervious to the action of the liquid and which does not in any way affect the taste of the liquid that has passed therethrough,

In previous siphon bottle heads it has been customary to use disk or plug valves either with or without a rubber seating surface for engagement against a metal valve seat. In operation in a siphon bottle head the use of such valves results in volently breaking up the liquid in passing the valve, with consequent loss of a material amount of the gas. Since siphon bottles are also filled through their headSQthe same loss of gas occurs as when'the liquid is discharged through the head, and for the same reason. Ordinarily the liquid is now charged with considerably more gas than is necessary prior to injecting it into 5 the bottles in order to insure a sufficient gas content in the liquid when it is in the bottle to compensate for the gas that is lost in filling the bottles. With my invention, there is practically no loss ofgas in" filling'the'bottle"although the 10 same filling process is used due to my improved valve construction that permits an absolutely free flow of the liquid into the bottles without breaking up'th'e liquid. Also in closing the valve, a soft rubber to!" rubber seat is effected that insures against leakage','irrespective of minor variations, and there is practically no wear whatsoever at the point of sealing. q

In detail my improved siphon bottle head comprises a main body portion I of any metal suitable for casting-which body portion is generally T'-shaped, thevertical leg 2 being recessed at 2' and interiorly threaded to thre'a'dedly engage over the neck 3 of an ordinarysiphon bottle. The cross arm of the body is provided at one end with a horizontally extending outwardly opening recess 4 of 'elliptical'cross section and the opposite end of the cross'arm'is formed to provide a generally downwardly extending discharge nozzle or spout 5 with a bore 6 therethrough opening at its inner end into a recess! that communicates with the; upper end of the recess 2'. A vertical-wall 8 disposed within the recess arm of the bodyand slightly to one side of the vertical axis'of the body forms a partition-between the inner end of recess 4 and recess 1, and a portion-9 ofthe lower wallof recess 4 extends across a portion of the recess 2"and connects with the lower edge of partition wall 8, the bottom surface of this portion 9 being horizontal 40 andfiat. I I v The inner opposite sides of recess 1 adjacent its'juncture with recess 2" are shouldered at I0 (Fig. 4) toprovide horizontal, flat, downwardly facing surfaces extending longitudinally of the cross arm from opposite ends of the wall 8, and the portion 9 is cut away at its opposite edges as at l l to provide a slight continuation of the shoulder [0. Against this shoulder I0 is seated a removable semi-annular flat piece I2 (Figs. 2, 8) the lower fiat side of said piece being flush with the lower fiat side of the portion 9 that extends over recess '2', thus forming with the portion 9 an annular 'flat seat around the upper end ofrecess 2'.

The conduit through said body comprises a rubber tube molded to provide a horizontally extending tubular portion 13 turned downwardly at one end to provide a vertical tubular portion I 4, and the lower end of the portion I4 is outwardly flanged at I5 to provide a circular disk of an outer diameter adapted to firmly seat around upper margin against the fiat surface formed by member I2 and portion 9. The conduit including the flange I5 is shown in Fig. 5 before it is inserted into the head, and is=made in thermal:- ner there shown for the purpose ofiacilitating the molding operation.

When positioned within the body of the siphon head, the portion I3 of the conduit is fished through the bore 6 of the arm 5 from the inside by means of any suitable instrument; such" as a Wire with a clamp at one end (not'ishown) al-'-- though it may easily be inserted by use of the fingers of the hand. When in the bore 6; the outer end oi theconduit terminates-adjacent the outer. end of bore= Ii, the inner-'sicleot the: outer endof said borebeing slightly taperedbutwardly; A short tapered sleeve I6.-is inserted in the-outer open end of the. conduit. whichsleevehas au outwardly projectingaflange I-I around.-its:.-outer end adapted :to extend over the outer fendiofi nozzle or spout 5, and annular caprla centrally-apertured about the size oflthe innerdecimeter of sleeve: I6 with an inwardly. turned flange IQ-defining'the edge of the aperture is adapted. tothreadedly-em gage threads: 20: on the outer sidesof the nozzle-5 atits outer end.-.

The roller 20- issupported in-the-*head.inthe position described, on spaced. horizontal arms 2 I (see. Fig. 7) These' arms extend through spaced rectangular openings 22 in the wall 8-=transversely acrosstherportion J4 of therrubber'oonduit -and are slotted as. at- 23 with vertical openings 24 f at the ends of the slots for receiving :thestub ishafits 25 at theopposi-te-endsofitheroller:20; The arms are connected at their ends oppositertheslotsaby an elliptical disk or cross bar 26 that is adapted to slidably fit in the recess 4. The outer side of bar 26 has a semi-cylindrical, horizontally-elongated projection 21 thereon adapted to fit in a similarly shaped recess 28 in the upper end of a generally downwardly extending lever 29 when the bar 26 is in the recess 4, the upper end of said lever being provided with a semi-cylindrical, horizontally-extending projection 3| adapted to fit in a similarly formed downwardly opening recess 32 formed in an extension 3| of the top of the body of the siphon head.

In installing the roller and its operating parts, axcoil spring 33 is first slipped over each arm 2 I, the arms are then inserted into the recess 4 and through openings 22 in wall 8 and the spring is compressed by'forcing cross bar 26 into recess 4 until the open ends 24 of slots 23 clear the side of the portion I4 of the rubber conduit opposite the side of said portion that is adjacent wall 8. Asside-of flange I5- is pulled down to permit'insertionof the roller 2Ilto above the arms 2I when the stub tshafts 25 of the-roller will drop through theopenings-24 of arms 2I into slot- 23.

'Ilhe projection 3| of the lever 29-is then insei-ted-in-recess 32 and upon releasing the 'pres-" sure on cross bar. 26 the projectionZ'l will enter recess 28 in the leverand the end 32 of the body oi 'the'-siphon'head will engage against a shoulder 35: of the-lever 29, thus retaining the lever against separation from the head and retaining all partsin assembled relation with the roller 20 tightly: squeezing the portion I 4 of the rubber conduit together to seal it against leakage past this-.-.point.

Thehead is. then screwed onto the neck 3- of thesiphon bottle and flange I5 of the conduit acts as a washer against flange 36 that is secured t'o the upper end of glass tube-3T through whichthe liquid is forced by gas pressure within the bottle: The' axis of'the-bore of tube 31 is in alignment directly belowthe lower-open end of the portion I4 of therubb'er conduit in'the-siphon head'and upon pressing downwardly on lever 29 theportion llnisiopened': and the. liquid will pass directly, into the conduit and therethrough and out of nozzle-5 withoutlanysharp corners or any. obstacles or projections in the passageway'to'cause breaking uproflthe'liquid.andconsequent loss of gas. Obviously, in filling the bottle through the nozzle, the same-smooth flow of liquid into the bottle will result.

The devlcerof "this invention has inactual use resultedtin :the delivery ofan appreciably higher charged liquid than is possible 'in' any devices of whichI am? aware, and. the liquid may be keptin the bottle indefinitely without loss of gasrdueto the-absolute". seal of the conduit at the point of theairoller. Also liquid of a much lower'gas content'may-"befinjected into the bottle through my nozzle for obtaining the desired character of liquid lnxthe container since it is not necessary to use thefhighly charged liquids now employed in orderito compensate for loss of gas in the-nozzle;
